I for one am going through quite a culture shock. I always assumed the nature of FOSS software made it immune to be confined within the policies of nations; I guess if one day the government of USA starts to think that its a security concers for china to use and contribute to core opensource software created by its citizens or based in their boundaries, they might strongarm FOSS communities and projects to make their software exclude them in someway or worse declare GPL software a threat to national security.
China is too important a supplier to the West. Sanctions against them would lead to retaliatory sanctions against the West from China which would be economically devastating.
Obviously they are just as dangerous and as actively involved is espionage as the other world players, but they hold too many cards to risk escalation. The West is also too important to their economy to escalate beyond war games. At least - we all hope so.
